Adapter for a rolling assembly having an axis of rotation comprising a tire having two beads, a rim with rim well (13) between two rim seats (12) each with an axially outer end, and width W between axially outer ends of these rim seats. The adapter, coupled between each bead and each rim seat, has two axially outer ends (2) each comprising seat (3) and bearing face (4) in a plane perpendicular to the axis of rotation. Body (5) connects outer axial ends (2) and comprises a main reinforcement, face (16) in contact with each seat (12) and with well (13) and positioned radially on the inside. The adapter has a total axial width L between each seat (3), and 60%W/L20%. Body (5) comprises immobilizing element (8) to wedge the adapter in the rim well (13).

A variable track wheel comprises a rim suitable for receiving a tire, and a disc through which said wheel is mountable on a hub, said disc being removably secured by fastenings to a connecting member provided in said rim, said connecting member projecting towards a rotation axis of said wheel, said wheel further comprising a plurality of spacers interposed between an annular perimeter zone of said disc and said connecting member of said rim, said disc and said rim being mountable in a plurality of reciprocal axial positions and in a plurality of reciprocal orientations to obtain a variation in the track of said wheel, said wheel further comprising at least one centering device for mutual positioning of said disc and of said rim said centering device comprising a hole and a pin said hole or said pin being provided in said connecting member or in said disc said centering device further comprising a coupling element so conformed as to cooperate with said hole and with said pin for reciprocally coupling said pin and said hole.
